TO ALL WHOM IT MAY CONCERN:

Be it known that I, YVILLIAM H. ARMSTRONG, of New Brunswick, in thecountyof Middlesex, and State of New Jersey, have invented a new andimproved Combination of a Range and Air-Heating Furnace; and I do herebydeclare that the following isa full, clear, and exact descriptionthereof, which will enable others skilled in the art to make and use thesame, reference being bad to the accompanying drawings, forming part ofthis specification, in which- V 'Figure 1 is a front view of myinvention partly in section. V

Figure 2, a transverse vertical section of the same taken in the linexx, fig. 1.'

Figure 3, a horizontal section of the same taken in the line yy, fig. 1.

Similar letters of reference indicate like parts.

This invention consists in arranging an upright range in a fire-place,in such a manner that the former may perform its legitimate functions ofcooking, baking, lite, and at the same time be made to perform thefunction of an air-heater or furnace, and also as a water-heater.

The object of'the invention is to combine a range and air-heatingfurnace at a cost not materiallyexceeding that of the range alone, andeconomize in fuel by utilizing all'the heat radiated from the range.

A represents the lower part of an upright range. 13 the top plate,provided with the usual potholes a. C is the fire-grate, having awater-back, D, and EE are the air-passages, one at each side of thefire-grate. F G are ovens, placed one. over the other, and surrounded bya flue, H, and I is a warming-chamber above the oven Gr, having the flueH extending underneath it, the smoke pipe J communicating with H at therear of the chamber I, as shown in fig. 2. The lower-end of flue Hcommunicates with the fire-grate G. The range is not new in itself,being now in general use and giving perfect satisfaction. The range isfitted within a'fire-place, K, of masonry, the front portion of thelower part A of the range which contains the fire-grate 0 being in frontof the fire-place, the part A extending the whole width of K, and alsothe warming-chamber I; flanges L extending from the ovens F G, to thesides of K, so as to completely fill up the front of the latter and formhot-air or air-heating chambers M M, at each side of the ovens,F G, thelatter extending back to the rear wall of K. The warming-chamber I doesnot extend backward so far as the oven, and the space-at the rear of thelatter forms a communication between the" upper parts of the chambers MM. NN are hot-air pipes leading from the upper parts of M M to the roomsor compartments to be heated; the cold air entering and passing throughEE at each side of the fire-grate G, into the lower part of M M, and inits passage upward through the latter becoming heated. The lower partsof" the chambers M M areconnected, as there is a space underneath thedoor G, and this space has a coil of pipe, O, placed in it whichcommunicates with the watewback D. This coil 6t pipe serves as animportant auxiliary to'the water-back, increasing its heating surfacevery materially, as it is entirely within the hot-air chamber. Theinduction and eduction pipes are connected with the water-back as usual,and therefore do not require a special description. The lowerpart of thefiue H, at the rear of tho fire-grate C, rests upon an edge of masonry,a and additional supports may be employed if desired. Bythis arrangementit will be seen I combine an upright range and a hot-air, or air-heatingfurnace at a trifling expense, not materiallyexceeding the cost of therange alone. All the heat radiated from the range is utilized with theexception ofithat radiated directly from the front. I Havingthusdescribed my invention, what I claim as new, and desire to secure byLetters Patent, is

The arrangement of the cooking range and its appurtenances AB C F G,flue H, chambers IMVM, airpassages E E, water-back D, and auxiliary pipe0, as herein described and for the purpose specified.

The above specification of ly invention signed by me this day of March,1866.

Y WILLIAM H. ARMSTRONG.
